Got this issue recently when Polybase engine didn’t start,it would attempt to start and then fail with connectivity error typical of the SQL server database engine. The solution in this case was simple to Enabled TCP/IP protocol for the database server. I also had to disable the firewall to confirm that ports weren’t blocked.
